You can use this tool while uploading data from legacy system into R/3 environment or to create and upload master data of huge amount. This tool follows a step-by-step procedure of 14 steps to create the master data into the system.

Considerations: Before you proceed

There are following considerations which must be taken into account before you proceed with this tool:

  • SAP customization is already performed.
  • Transaction to be carried out is identified.
  • Examine carefully which fields in legacy file are mandatory and which can be left as optional from the SAP system point of view.
  • Comparison of functions between the legacy system and the SAP system must have been completed. As a result of comparison, the data to be migrated is determined.

 

 

Project preparation: Creating Project, Subproject and Object

Project: The project serves as an organizational unit used to combine mapping and field assignments.

Subproject: It is subordinated to the Project. For example, if project comprises of complete migration data for an organization which comprises of severalplant, then subproject comprises the data in the individual plants.

Object: A business object, which is used to transfer the data of a project to the SAP system.

 

  • Enter Transaction code – ‘LSMW’.

LSM Workbench: Process Steps

Master data upload through this tool comprises of following 14 steps procedure:

 

Step 1: Maintain Object Attributes

  • Start the data upload process by selecting the first step radio button--> Execute

untitled18.JPG

 

By default, Object Attributes will be in ‘Display’ mode.

There are four Modes of Data Transfer :

  1. Standard/ Batch Input : Standard upload Programs
  2. Batch Input Recording : Here you can create a recording of your own and use it to upload / change data
  3. BAPIs : Standard BAPIs are used to upload Data
  4. IDOCs : Any Inbound IDOC function modules can be used to process the data

  Here, we are using ‘Batch Input Recording’ method to upload master data.

  • Select ‘Display <-> Change’ button and get it in change mode.

 

untitled20.JPG

 

  • Enter the Recording which was created through beginning steps, i.e. ‘REC_EQUIP’ and click on ‘Save’.

 

 

untitled21.JPG

 

When the first step is completed, the system takes you to previous screen and populates the field against it.

Step 2: Maintain Source Structures

 

Source structures can be used to design the hierarchy of the files to be uploaded. However, here highest hierarchy level is sufficient. Structures are prerequisites for Maintaining Source Fields.

  • Select the next step radio button and Execute. System then takes you to ‘Display’ mode of Source Structure.

 

untitled23.JPG

  • In ‘Change’ mode give the ‘Source Structure’ and ‘Description’.

 

 

untitled24.JPG

 

  • System shows the Source Structure created. ‘Save’ and go back.

Step 3: Maintain Source Fields

 

Source Fields are maintained in Source Structures.

 

  • Click button ‘Object Overview’ and select Table View.

 

 

untitled26.JPG

 

  • From Table view, select ‘TABNAME’, ‘Type’ and ‘Length’ and maintain the excel sheet.

untitled50.JPG

 

  • Now Save and go back.

 

 

Step 9: Read Data

 

Here our data which is uploaded by the file would be read.

  • Click on ‘Execute’ and the data read status and number of records would be displayed on the screen.

untitled52.JPG

 

Step 10: Display Read Data

 

Here, we can display the records which were read in previous step.

 

untitled53.JPG

 

  • Check, whether data has been correctly fit into fields. We can also give the line selection based on need.

 

 

untitled54.JPG

 

Step 11: Convert Data

 

Here,  the legacy data is converted into SAP standards. We can check the data converted later on.

 

untitled55.JPG

 

  • Click on ‘Execute’ button and system displays the status for the data conversion.

Note: Check the number of records from Step 9. Both should be same.

Step 12: Display Converted Data

 

Executing this step displays the data converted in the previous step.

 

untitled59.JPG

  • Click on any record to check the converted data.

  Note: Here the visual check can be performed to check the values lifted by the file against the fields of SAP to be correct and as per requirements.
